Genesis 2:2-3
2  And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
3  And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.

Leviticus 23:3
Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the LORD in all your dwellings.
